Invariant data is information that remains constant and unchanging despite varying circumstances or conditions. This type of data is often used as a reference point or baseline for comparison in various analyses or applications.

What is a repository for definitions of data processes data flows data stores and data elements.?

A data dictionary is a repository that contains definitions of data processes, data flows, data stores, and data elements used in an organization. It helps to provide a common understanding of data terminologies and structures within a dataset or system. Data dictionaries are often used to maintain consistency and clarity in data management and analysis processes.


What is metadata what is its use in data warehouse architecture?

Metadata is data about data that provides information such as the structure, format, and characteristics of the data stored in a data warehouse. It is used in data warehouse architecture to facilitate data integration, data governance, and data lineage. Metadata helps users understand and manage the data in the data warehouse efficiently.


What is explicit data and implicit data?

Explicit data is data that is clearly stated or defined, while implicit data is implied or hinted at. Explicit data is typically straightforward and directly provided, whereas implicit data requires context or interpretation to understand its meaning. In the context of programming, explicit data is data that is clearly declared and specified, while implicit data is data that is inferred or derived.


Is a logical unit of data and is a physical unit of data?

A logical unit of data is a virtual representation of data while a physical unit of data is the actual storage of data on a physical device. The logical unit of data is how data is organized and manipulated from a software perspective, while the physical unit of data is how data is stored on hardware such as disks or memory.


What are the Data staging steps in data warehousing?

Data staging in data warehousing involves steps like data extraction from source systems, data transformation to prepare it for analysis, and data loading into the data warehouse. This process ensures that data is cleansed, standardized, and organized before being stored in the data warehouse for reporting and analytics purposes.

What is a Zeuthen-Segre invariant?

The Zeuthen-Segre invariant is a numerical invariant of an algebraic surface, denoted by Z(P), where P is a smooth projective surface. It is calculated using the intersection theory of surfaces and is used to distinguish between surfaces in the same deformation class.


How do you use set and get in object-oriented programming?

A set function (or setter) is an object mutator. You use it to modify a property of an object such that the object's invariant is maintained. If the object has no invariant, a setter is not required. A get function (or getter) is an object accessor. You use it to obtain a property from an object such that the object's invariant is maintained. If the object has no invariant, you do not need a getter.


How do you find the invariant line of a stretch?

To find the invariant line of a stretch, identify the direction in which the stretch occurs. The invariant line is typically the line that remains unchanged during the transformation, often along the axis of the stretch. For example, if stretching occurs along the x-axis, the invariant line would be the y-axis (or any line parallel to it). You can confirm this by observing that points on the invariant line do not change their position under the stretch transformation.

How to know that linear differential equation is time invariant or time variant?

If the coefficients of the linear differential equation are dependent on time, then it is time variant otherwise it is time invariant. E.g: 3 * dx/dt + x = 0 is time invariant 3t * dx/dt + x = 0 is time variant

Practical example for Time-invariant system?

System whose domain is not in time can be a time invariant system. Ex: taking photo to a fixed object. here domain is not in time so photo wont change with time
